Description

TECHNICAL FIELD

[0002] As prokaryotes, algae can perform photosynthesis, converting carbon dioxide and water into organic matter and oxygen using light energy. Light is the main energy source for algae to perform photosynthesis. Light intensity directly affects the photosynthesis rate of algae. In the case of sufficient light, the photosynthesis efficiency of algae is improved, thereby accelerating its growth and reproduction. However, the overpopulation of algae will form "water bloom", covering the water surface and hindering the gas exchange between water and air, resulting in a decrease in dissolved oxygen in water and affecting water quality. The overpopulation of algae will squeeze the living space of aquatic plants and destroy the balance of the aquatic ecosystem.

[0003] Therefore, the prior art reduces the light intensity on the surface of the water body by using sunshade nets, planting aquatic plants, and appropriately shortening the light time to reduce the photosynthesis time of algae, thereby reducing the growth rate of algae.

DETAILED DESCRIPTION

[0056] The application will be further described below in conjunction with the drawings and examples in the specification.

[0057] Example 1

[0058] This embodiment addresses the problem of algal blooms, which occur when algae proliferate and cover the water surface, hindering gas exchange between the water and air, leading to a decrease in dissolved oxygen and affecting water quality. It provides a floating photovoltaic algae control and oxygenation system.

[0059] like Figure 1 As shown, the floating photovoltaic algae control and oxygenation system includes a floating frame with a predetermined area. It should be noted that algae blooms in rivers and lakes are generally localized in area and region; therefore, the area of ​​the floating frame in this embodiment is determined based on the algae bloom area. Furthermore, for ease of independent operation and river / lake management, the floating frame in this embodiment is modular, comprising at least one set of floating frames 1. In other words, the floating frame is constructed by connecting the floating frames 1 according to a predetermined layout, such as... Figure 1 Matrix connection in the model.

[0060] Combination Figure 2 Each set of floating frames 1 is equipped with a transmission component 2, which is connected to a photovoltaic module 3. The photovoltaic module 3 is configured to install multiple photovoltaic panels, and the photovoltaic panels are dynamically laid out under the synergistic effect of the transmission component 2. The dynamic laying out involves switching between horizontal and inclined laying. When the photovoltaic panels are laid horizontally, sunlight is completely blocked, hindering algae photosynthesis and inhibiting their growth, thus effectively controlling algae. When the photovoltaic panels are laid inclined, the necessary operating space is provided for targeted water sampling and maintenance of the photovoltaic panels. The floating board in this embodiment needs to have high durability and be able to resist adverse factors such as water flow impact, ultraviolet radiation, and chemical corrosion. In terms of material selection, corrosion-resistant and aging-resistant polymer materials, such as polyethylene and polypropylene, can be used.

[0061] To fully utilize solar energy and simultaneously contribute to water environment protection, this embodiment also includes an aeration device installed at a designated location in the river or lake, preferably below or near the floating frame. The aeration device is electrically connected to the photovoltaic module 3 via a converter, allowing the photovoltaic module 3 to act as a power source for the aeration device, driving it to oxygenate the oxygen-deficient bottom water.

[0062] It is worth considering that cyanobacteria contain air sacs within their cells, providing buoyancy and allowing them to remain in the surface, sunlit areas of the water for extended periods. This characteristic of cyanobacteria must be taken into account when setting up the floating board to ensure its effective interception of algae floating on the surface. Therefore, this embodiment also includes: several piles, pre-driven into designated locations in the river or lake according to the laying area; that is, the bottom of the piles is pre-buried in the mud layer of the river or lake, while the top portion is exposed above the water surface. The top of the piles is connected to the floating frame 1 via a quick-installation structure for temporary positioning of the floating frame.

[0063] The embodiment utilizes the quick installation structure to realize the detachable connection of the floating frame 1 and the pile column, and the purpose is to realize the positioning of the floating frame 1, so as to overcome the wind force, water buoyancy and blue-green algae buoyancy. Meanwhile, it is convenient for installation and disassembly, and realizes the reuse of the floating photovoltaic algae control and oxygenation system. That is, after the current water area is managed and controlled, the algae disappears or the regional stability is short-term, the floating photovoltaic algae control and oxygenation system can be quickly disassembled. The disassembled floating photovoltaic algae control and oxygenation system can be transferred to other water areas, and the quick disassembly structure is used for reinstallation and reuse.

[0064] In combination Figure 3 , the quick installation structure in the embodiment comprises a fixed pin 101 for being embedded in the top end of the pile column, and the top surface of the fixed pin 101 is recessed downward by a predetermined depth to form a stepped cavity 102. On the outside, the top is provided with an annular limiting protrusion 103, and a plurality of columnar grooves 104 are equidistantly arranged below the annular limiting protrusion 103, and a ball 105 is movably arranged in each columnar groove 104.

[0065] The outer wall of the fixed pin 101 is further provided with a clamping sleeve 106, the clamping sleeve 106 is elastically connected with a shaft sleeve 107 through a spring 108, and the shaft sleeve 107 is movably sleeved on the fixed pin 101. Correspondingly, the inner wall of the shaft sleeve 107 is provided with an annular operation protrusion 109, and the inner wall of the annular operation protrusion 109 is a wedge structure.

[0066] And it also comprises a plug 110 with a resisting end 110-a and an operation end 110-b, as shown in Figure 4 , wherein the outer diameter of the operation end 110-b is greater than that of the resisting end 110-a. The outer wall of the resisting end 110-a is provided with an annular groove 110-c at a specified position, and the floating frame 1 is provided with an operation hole at a specified position, which is matched with the operation end 110-b. The inner diameter of the operation hole is equal to the outer diameter of the operation end 110-b. In use, the plug 110 passes through the operation hole on the floating frame 1, so that the operation end 110-b is movably arranged in the operation hole, and the resisting end 110-a is arranged in the stepped cavity 102 according to the requirement.

[0067] In combination Figure 4 and Figure 5 , when locked, the resisting end 110-a of the plug 110 is located in the stepped cavity 102, the ball 105 is clamped with the annular groove 110-c, the spring 108 is reset, and the shaft sleeve 107 moves upward to press the ball 105 through the annular operation protrusion 109; when disassembled, an external force is applied to the plug 110 (upward pulling), the ball 105 is forced to move outward to reversely press the annular operation protrusion 109, the shaft sleeve 107 moves downward due to the wedge structure until the ball 105 is completely separated from the annular groove 110-c, and the spring 108 is in a compressed state.

[0068] In another embodiment, the transmission assembly 2 comprises: two sets of guide rails 201 arranged on the upper surface of the floating frame 1 on both sides in the length direction, and two sets of sliding assemblies arranged on the corresponding guide rails 201 respectively. In order to realize the real-time adjustment of the installation plate state, first, a rack 202 is arranged on the inner wall of the floating frame 1 in the length direction, and then a driving trolley 203, at least one set of driven trolleys 204, a positioning trolley 205 and at least three trusses 206 are arranged in sequence. The connection relationship between the truss 206 and the trolley can be referred to Figure 2 It is understood that the driving trolley 203 in the two sets of sliding assemblies is connected with the driving trolley 203, the driven trolley 204 is connected with the driven trolley 204, and the positioning trolley 205 is connected with the positioning trolley 205.

[0069] In order to realize the relevance of the truss 206 and simultaneously drive all the photovoltaic panels in the floating frame 1, the photovoltaic assembly 3 comprises: a plurality of hinged assemblies arranged between adjacent two sets of trusses 206; each hinged assembly comprises: a first installation plate 301 and a second installation plate 302 hinged to each other, and the other side of the first installation plate 301 and the second installation plate 302 is hinged to the adjacent truss 206. Wherein, the first installation plate 301 and the second installation plate 302 are provided with a plurality of positioning grooves, and the positioning grooves are arranged to install solar panels 4 of corresponding size.

[0070] Taking the direction of the driving trolley 203 as the first end and the direction of the positioning trolley 205 as the last end. In use, the driving trolley 203 is used as a power source to control the position and angle of the installation plate connected therewith and simultaneously realize the first end positioning; the driven trolley 204 controls the position and angle of the installation plate between the driven trolley 204 and the driven trolley 204 / positioning trolley 205 under the joint action of the driving trolley and the hinged assembly; the positioning trolley 205 is used to realize the positioning connection of the last hinged assembly, i.e. the last end positioning.

[0071] For example, when the photovoltaic panel needs to be laid out with the maximum area, the driving trolley 203 leads the corresponding hinged assembly, the corresponding hinged assembly leads the driven trolley 204, and the first installation plate 301 and the second installation plate 302 in the hinged assembly are unfolded in sequence. Conversely, when the photovoltaic panel needs to be stored and part of the water surface is exposed, the driving trolley 203 is controlled to move in the opposite direction, leading the corresponding hinged assembly, the corresponding hinged assembly leading the driven trolley 204, and the first installation plate 301 and the second installation plate 302 in the hinged assembly are folded in sequence. The folding angle can be determined according to the requirement.

[0072] In order to meet the above requirements, such as Figure 5 and Figure 6The shown active trolley 203 includes: a main bearing plate 203-a, the inner side of which is vertically fixed with a main mounting plate 203-b. A driving motor 203-c is installed on the upper surface of the main bearing plate 203-a, and at least four groups of guide wheels 203-d are arranged on the lower surface of the main bearing plate 203-a. In this embodiment, four groups of guide wheels 203-d are symmetrically arranged on both sides of the guide rail 201 and are in surface contact with the guide rail 201.

[0073] A rotatable rotary gear 203-e is installed on the outer side wall of the main mounting plate 203-b, which is drivingly connected to the output shaft of the driving motor 203-c and is in meshing engagement with the rack 202. In this embodiment, the driving connection between the rotary gear 203-e and the output shaft of the driving motor 203-c can be achieved by the gear and rack 202, which will not be described in detail here.

[0074] In order to ensure the stability of movement, a plurality of rotatable support wheels 203-f are also installed on the outer side wall of the main mounting plate 203-b, the rolling surface of the support wheel 203-f is in contact with the floating frame 1, which is used to provide a certain supporting force to increase the stability.

[0075] When the active trolley 203 moves towards the head end, if it cannot stop moving quickly when it reaches the head end, not only will the trolley itself be damaged, but also the connection between the first mounting plate 301 and the second mounting plate 302 in the hinged assembly will be broken due to excessive pulling, causing irreversible damage.

[0076] Therefore, the active trolley 203 further includes: a limit switch 207 arranged in the forward direction, which is used to perceive the floating frame 1 and send a signal to turn off the driving motor 203-c. Figure 7 As shown, the limit switch 207 includes: a body 207-a installed at the head end of the main mounting plate 203-b, a bracket 207-b fixed on the body 207-a at a predetermined angle by a tensioning bolt, and an infrared sensor 207-d installed above the bracket 207-b. When the bracket 207-b remains at the predetermined angle, the infrared sensor 207-d detects no obstruction; if the bracket 207-b is rotated clockwise by the trigger bar 207-c under external force, the infrared sensor 207-d detects that there is an obstruction, triggering a signal to turn off the driving motor 203-c. This can effectively protect the active trolley 203 and other components of the floating photovoltaic algae control oxygenation system, prolonging the service life.

[0077] In order to reduce the wear of the trigger bar 207-c, a 207-e is installed at the head end thereof.

[0078] In another embodiment, in combination with Figure 8The driven trolley 204 comprises a sub-carrier plate 204-a, a sub-mounting plate 204-b vertically fixed inside the sub-carrier plate 204-a, at least four groups of guide wheels 203-d arranged on the lower surface of the sub-carrier plate 204-a, the guide wheels 203-d being symmetrically arranged on both sides of the guide rail 201 and in surface contact with the guide rail 201, and a plurality of supporting wheels 203-f rotatably mounted on the outer side wall of the sub-mounting plate 204-b, the rolling surface of the supporting wheel 203-f being in contact with the floating frame 1.

[0079] Correspondingly, the positioning trolley 205 of the embodiment is increased with a fixed clamping block 205-a on the basis of the driven trolley 204, and is fixedly installed on the floating frame 1 and located at the leading end of the positioning trolley 205, so as to realize long-time positioning, as shown in Figure 9

[0080] Considering that the driven trolley 204 is easy to move when positioned without constraint, the truss 206 is forced to move when the driven trolley 204 stops at a certain position, such as in the case of strong wind. Non-controlled movement of any one driven trolley 204 will directly cause the connection between the mounting plate and the driven trolley 204 to break, especially when the photovoltaic panel is arranged in an inclined manner.

[0081] In order to solve the above technical problems, in another embodiment, the driven trolley 204 is also provided with a positioning assembly. As shown in Figure 9 The positioning assembly comprises a connecting frame 204-c fixed on the sub-carrier plate 204-a, and a push cylinder 204-d hinged on the connecting frame 204-c. It also comprises a pressing plate 204-e hinged at one end on the sub-mounting plate 204-b, and the pressing plate 204-e is hinged with the output end of the push cylinder 204-d at the same time. When the push cylinder 204-d is pushed out, the other end of the pressing plate 204-e is in abutment with the side surface of the guide rail 201, and the positioning is realized by increasing the friction force, and when the driven trolley 204 moves, the push cylinder 204-d is in a compressed state.

[0085] ​When the algae outbreak, the transmission assembly drive photovoltaic components in the horizontal laying state, that is, the photovoltaic board between each other is first connected, the sun and the algae are effectively separated. That is, by driving the main trolley to the head end through the transmission assembly until the photovoltaic board is in a horizontal position, and each group of driven trolley is positioned by using the compression assembly.

[0086] When the water body under the photovoltaic board or the photovoltaic board itself is required to be operated, the corresponding transmission assembly is selected to drive the photovoltaic board in the photovoltaic assembly to lay according to a predetermined angle, that is, the photovoltaic board is gathered together to expose part of the water body;
